Scared and confused

So the docs told me that my baby has fluid around the brain and neck and said I have to see a specialist and to keep my options open....I've done my research and can't find anything on my current situation. All I see is babies and elderly with the condition but none in the womb...has anyone heard of this or gone through it or know someone that's gone through it? I'm really scared an just want my baby to be ok...I'm 17 weeks and 5 days
